Why it works: Flour and raisin match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Superior Fruit Cake
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the batter
Preheat the oven to 300°F (150°C).
In a large bowl, mix the flour, butter, and sugar until well combined.
Add the raisins, currants, almonds, and citron to the mixture.
In a separate bowl, beat the eggs lightly and then add them to the mixture.
Stir in the allspice, cloves, cinnamon, nutmeg, wine, brandy, molasses, and dissolved baking soda.
If necessary, add more flour after incorporating the fruit.
Bake and finish
Butter a sheet of parchment paper and line a baking pan with it.
Layer slices of citron and the fruit mixture in the pan until nearly full.
Bake for 3 to 4 hours, depending on the thickness of the loaves.
Let the cake cool gradually in the oven, then ice when completely cool.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the structure that holds the heavy fruit and batter together.
- Butter
- Adds richness and tenderness to the crumb.
- Eggs
- Bind the batter and add structure as they set during baking.
- Raisins
- Add moisture and chewy sweetness throughout the loaf.
- Molasses
- Adds dark color, moisture, and deep caramel-like flavor.
- Baking powder
- Releases gas that lifts the batter as it heats.
The step that matters
Bake slowly and cool in the oven. A dense, fruit-heavy batter needs low, long heat so the center sets without the outside burning. Cooling gradually in the oven helps prevent cracking and sinking as the structure firms up.
Swap the currant
How well each one fits the dish's main ingredients (flour, butter, sugar, raisin, almond, egg, allspice):
- Vanillafits better
- Figfits better
- Lemonfits better
- Currantthe original
Fit is the average pairing score against flour, butter, sugar, raisin, almond, egg, allspice. Candidates are from the same food group and used in at least 100 recipes.
